LH45X Flow Control Check Valve is primarily used in multi-pump parallel systems, adjusting flow rate by changing the number of units. Installed at the pump outlet, it can limit flow, stabilize head, and prevent overload of the motor by avoiding low head and high flow conditions during pump operation.

Applicable scenarios

Ideal for industries such as chemicals, liquefied petroleum gas, vehicle and ship manufacturing, water treatment, and electricity, particularly effective in pump export flow control.
